If you look at the big picture if your going to make something all motor the ls motor no non vtec anyway is the way to go. It can run a bigger came lobe the whole time, Like the v8 guys do. Instead of having a sissy cam lobe down low and a big one up top.

I migh take up a vtec killer project some time in the future. But thats just a thought and i have tomany of those already.
